ABC News’ Martha Raddatz interviews Sen. Chris Van Hollen on “This Week" over President Trump deploying the National Guard to Washington, D.C.

Nearly 400 arrests have been made since President Donald Trump declared a public safety emergency in the District and activated National Guard troops to assist local law enforcement, according to Attorney General Pam Bondi.

The Republican governors of West Virginia, South Carolina and Ohio announced Saturday they will send National Guard troops to Washington, DC, in an escalation of President Donald Trump’s efforts to federally take over law enforcement in the city.

DeWine said the troops are expected to arrive in D.C. in the coming days and emphasized that none of them currently serve as active law enforcement officers in Ohio.

Trump's plan to address crime in D.C. calls for deploying National Guard troops along the National Mall overnight Wednesday into Thursday morning, according to a source.

President Donald Trump deployed 800 National Guard troops to the nation's capital as part of a crime crackdown in the city.

In New Mexico’s most populous city, National Guard troops are listening to the police dispatch calls, monitoring traffic cameras and helping to secure crime scene perimeters, tasks not usually part of the job.

Trump fulfills campaign promise by federalizing D.C. with 30-day emergency control, cracking down on crime in the nation's capital.
